[jira] [Issue Comment Edited] (MAHOUT-778) Mark folder name of
final clustering iteration with pattern such as 'cluster-n-last'
[ https://issues.apache.org/jira/browse/MAHOUT-778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13115998#comment-13115998 ]

+1 for the done marker
I modified ClustersFilter from examples (Used by the Display* Classes).
You can pass a Configuration object and a cluster output Path to the constructor and it will accept the last iteration path if the done marker is present. Otherwise it accepts 'clusters-0'.
Let me know what you think.
There is still the problem that you need to pass in the exact last iteration path to ClusterDumper. If the last iteration path is renamed to 'clusters-n-done' you can use a glob for command line Mahout:
{code}
--output=clusters-*-done
{code}
but this would break existing things.

> It would be useful if the KMeans, FuzzyKMeans would specify the last cluster iteration folder with a pattern such as 'cluster-n-last'.
> At the moment it is difficult to configure other programs to process clustering results since the number of actual iterations is not known up front.
> A PathFilder similar to ClustersFilter could be created which filters folders on the pattern 'cluster-*-last' in order to determine the folder.
